Controlling Five Servos

Projects General Guidance
1

Good Day everyone!!! Seems I have a problem controlling five servos in my project, everytime i control one servo the other servo also moves, I have already assigned each servo to each PWM pins and the five potentiometers that controls them on different analog inputs, i will post my code and i am open for any suggestions if there is any mistakes or code to change, also i am using a 5V DC-DC buck boost connected in a 9V Fly Back power supply. Thank you!!!

#include <Servo.h>

Servo servo4;
Servo servo5;

Please post complete wiring diagram (NOT FRITZING, those are unreadable spaghetti).

Do you have grounds connected?

Oh, and look into using arrays instead of numbering your variables. Makes for much cleaner code.

thank you! sorry for disturbing, I have solved the problem, its all ok now :slight_smile: thanks!!!

So share what the problem and solution were; that may help others in future.

Yes, please do post the solution. Even a simple 'i did not connect the grounds' helps if that was the fix.
Also, you really need to think about using arrays. When you start putting numbers after variables, it is time to use arrays.
Also, autoformat your code. It makes it much easier to see logicall blocks of code. Try it. CTRL-T in the editor.
